Missed period but had some spotting, pregnant?

a

My period was due November 21. I’ve had some spotting and one day of bleeding last week and that was it. My periods have been a bit irregular but I still always know when they’re coming. I had all of my symptoms but no period. I’m now 25 days late but nothing is coming up on a hpt. I’m getting blood tests on Monday. Does this seem like I may be? I hope. It says my chance of pregnancy for the 20th was high. Fingers crossed.
